VMSStreamerQt

Qt C++ app for streaming and plotting Quaraze data from a plain FTP server (no FTPS).

Build

Makefile (recommended)

cd VMSStreamerQt
make build
make open   # macOS

CMake

cd VMSStreamerQt
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/opt/homebrew/opt/qt
cmake --build build

Run

open build/VMSstreamerQt.app

Release (GitHub Actions)

Tag a version to produce macOS/Windows/Linux release assets:

git tag v0.1.0
git push origin v0.1.0

Artifacts produced:

• macOS: .dmg
• Windows: .msi
• Linux: .AppImage

macOS Signing & Notarization (for DMG)

To avoid the “app is damaged” Gatekeeper warning, set these GitHub secrets:

• MACOS_CERTIFICATE (base64 of your Developer ID Application .p12)
• MACOS_CERTIFICATE_PASSWORD
• MACOS_SIGN_IDENTITY (e.g. Developer ID Application: Your Name (TEAMID))
• APPLE_ID
• APPLE_TEAM_ID
• APPLE_APP_PASSWORD (App-specific password)

If these are not set, the DMG will be unsigned and macOS will show a warning.

Dependencies

• Qt 6 (Widgets, Charts)
• libcurl
• OpenSSL (Crypto) for Fernet decrypt

Credentials

The app expects credentials.json and (if encrypted) key.key next to the .app (or the executable).

Plaintext example:

{
  "ftp_host": "ftp.example.com",
  "ftp_user": "username",
  "ftp_pass": "password"
}

Encrypted credentials are supported (Fernet). If values start with gAAAA..., the app will load key.key and decrypt.

Notes

• FTP only (plain). If ftp_host uses ftps:// the app will show an error.
• CSV preview shows the first 100 rows.
• Plot uses TIMESTAMP column if available.
• Save plot to PNG/PDF.
